. Y Our invention relates to improvements in the class of repeaters and delivery terminal .conduitsltlierefonfor use as rolling/mill gui-des,` It has lfor fitsy object toA provide simple, efficient and durablemeans for effect- Y ing properfdelivery ofthe blank Vin its passage fromlthe reducing pass of-one pair yof rolls, around. a guiding repeater' .or reversing mechanism, andv then-'through one or the lo other of ,our improved :delivery terminals to f anotherreducing pass.fof a secondV pair of.

rolls.

-Theimprovement is of thesame general type incertain respects as that lshowninthe f1.7 prior patent of leimer #1,577,412, of March 16,1926. v In guiding mechanism of the same general ln'nd,zwith a `continuous blank of the flat strip type subjected to continuous serial re- 512W duction, fand involving lreturn pass guiding Lmechanism, a tortional twist is ordinarly imparted to the blank, tending to vary its-delivery position on entering' the knext subsequent pass for the following reduction, either .2 edgewise or iiatwise.. 'I Y y Y Our improvement herein relates particularly to guidingand controlling means by which the blank may be positively 'delivered tothe pass ofthe reducing rolls-continuously in :,3'0 thedesired position.

This object is eected by our-improvement -so constructing the delivery terminal, leading to the pass, in such a manner that it i 'will automatically deilect'theblank from an entering position, and in harmonyk withv or opposition. to any torsional movement imparted to it inpassing around the repeater. These objectsfare effected, in certain pre-V ferred constructions, by means ofthe mecha- V"lo'nism herein'illustratedufand,as further described. Y v Y Y Referring to the v'jdrawingsf showing such preferred constructions:` f f Y f Fig. 1 is aplanfview showing the applicai` f4.5, tion of the t'erminal'mechanism to the .receiving;y

such mill for present purposes'being designed The receiving section 4 .of the repeater is .of trough form, into which the blank enters,

a guide 51 of any suitable construction being utilized between itsreceiving end and the pair olf/rolls 2, if desired. The companion section 6 ofthe repeater effects a continuation of section 4, providing for U-shaped return of the blank in a reverse direction, and 90 spirally curvedwall of member 18a merges into aiiat delivery lip face 28, while 'the inner curved surface of member` 19a merges in a similar manner into a lower flatdelivery lip For the purpose of positively guiding and delivering the blankin a flatwise position, the

' end of the. Yupper wall is thus flattened and spaced above the flattened lower wall, with proper clearance. IVe also providethe vsupplemental delivery wings or gates 27 which form, by their inner surfaces, continuations 0f the inner side walls of members 18a andr By such construction we provide upper and lower substantially parallel faces at the outlet end of the delivery which the blank emerges.

- Guide wings 27 are providediwith rear terminal, lbetween rounded yterminal bearing Vedges 30y bearing backwardlyagainst correspondingly recessed receiving sockets 31, in the forward overlapping side edge portions of outer member 18a, whereby the wings may be moved inwardlyfor outwardly therein in the mannerA of hinges.

Each wing is provided with a lateral-lug 32 through which, by bolt 33, the wing may y .be secured iny its slot'26 in the desired position, 5 so'as to locate the terminalsv of the wings'at a0 j Y 1 necessary outlet opening space, with properk the .proper distance apart" t0 pIOVCle''llG/ clearance and coniiningaction. Y Y

As thus constructed, andvwhen properly adjusted to suit the strip being rolled, it will pass through the repeater 4 6 and copings' c 16 and 17, under the'continuing twisting action. Such action will tend to throw it overV and down flatwise in the directions indicated at cy and d ofIigglQ, whereby to einerge'in a proper iiatwise position for entrance between the flat face rolls 3a, as as.

s isted and controlled .by the terminal 7 a. f

It will be observed that by each of the constructions above described, we provide for positive guiding and, twisting of the blank, and without any liability to jamming or obstruction, while avoiding the undesirable objections of vertical slotsfbetween the side members ofthe terminal.- Thus,in both constructions, the joints between the two members forming the delivery terminal are lat- ,.eral rather than vertical, thus providing continuous integral upper and lower surfaces Vin a general longitudinal direction throughout, greatly assisting in free passage and unrestricted delivery ofthe blank to the rolls.

The general proportions, detail construction, size, or other features may be variously changed ormodified bythe skilled mechanic or designer to adapt'the invention to various conditions present iii rolling mill practice,

c but all such changes are to be understood as j within the scope of the following claims. j

.What we claim is l f c 1. In combination with the deliveryend of 2.`In; combination withthe delivery e a repeater.` trough forrolling mills,a delivery terminal composed yof, two interfitting shell members' oined'by a ,lateral seamy providing inner-:upperand lower continuous `bearing 'faces,l'o ne offjsaid members having its inner livery terminal shell secured to the base plate and provided with endmost inner parallel faces providing a delivery slot.

4. In combination with a base plate having a rear receiving coping and lateral attaching lugs, a two-part delivery shell connected with said lugs and provided with inner guiding lwalls and endmost inner parallel faces providing adelivery slot.

5.V In combination with a base plate having a rear receiving coping and lateral attaching lugs, al two-part delivery shell connected with said lugs and provided with inner guiding walls and endmost laterally adjustable walls providing a variable width delivery slot.

6. In combination with a base plate having at its rear end a guiding coping and atits forward end laterally extending slots, a twopart delivery shell mounted on the base provided with hinged side wall extensions and means for variably holding the extensions engagingy said slots.

7'.v In combination with a base plate having at its rear end a guiding coping and at its forward end laterally extending slots, a twopart delivery shell mounted on the base provided atthe front with hinge bearings, and sidewall tongue extensions engaging said bearings and provided with bolts engaging said slots.

8.
